Case of the week – 06-14: Delayed enhancement-targeted biopsy Clinical: A 53-yr-old ♂ with 2 types of symptomatic VT. One VT with LBBB and superior axis suggested origin from RV inflow, likely from IVS. Rest ECG shows inverted T waves inferiorly and no epsilon wave. EPS: normal coronaries; 3 VT morphologies, one resembling the clinical VT. CMR: No fatty infiltration on T1W. Normal RV & LV size & function (bright mid-myocardial signal on short axis SSFP cine is due to prior Gadolinium injection). Late Gd-imaging (IR-FLASH) shows mid-myocardial enhancement of the IVS (close to the inflow -arrowheads), anterior RV (arrow) and lateral LV walls. Biopsy: Targeted to the enhancing areas: fibro-fatty ARVD type histology. Perspective: Delayed enhancement on CMR may correspond to the arrhythmogenic foci. It may help target a biopsy. CMR system: 1.5 T Magnetom Avanto, Siemens, Germany.
